The working principle of the anti-falling braking device of the stacker is as follows:
when abnormal conditions occur, such as breakage of a steel wire rope or a chain of a speed limiter, the fixing ring 41 drives the swing rod 4, the swing rod 4 drives the other side of the same mechanism through the synchronous connecting rod 8, the same braking mechanisms on two sides synchronously operate, the pull rope 5 drives the helical gear block 3 to move upwards, the helical gear block 3 moves upwards simultaneously through the guiding and limiting of the braking fixing seat 2, the guiding rod 7 and the straight plate bearing 6 and is tightly attached to the upright post 1 of the stacker, and the helical gear block 3 is provided with the hook teeth 33, so that the falling process of the stacker-mounted cargo platform is locked, and the cargo platform is prevented from continuously falling.
When the locking is released, the inclined tooth block 3 can be restored to the original position only by manually controlling the upward movement of the stacking machine loading platform, and at the moment, the braking mechanism is released, so that the loading platform can be quickly restored to the original state.
According to the anti-falling braking device, the cargo carrying platform can stop falling under the condition that a chain is broken or a steel wire rope is broken, so that the safety of cargoes is ensured. The anti-falling braking device is fixed on the cargo carrying platform and can move vertically along with the cargo carrying platform, and the anti-falling braking device utilizes the self upright post 1 of the stacker as a braking guide rail, and achieves rapid braking when the cargo carrying platform falls down accidentally through the simple movable helical tooth block 3 with the hook tooth 33 and the lamination of the side surface of the upright post 1 of the stacker.
